Sensory Sensory Motor Motor Both Motor Both Sensory Both Both Motor Motor
31
Chemoreceptors
taste buds and olfactory epithelium
32
photoreceptors
rods and cones
33
thermoreceptors
temperature; respond to hot and cold
34
mechanoreceptors
corpuscles that sense pressure
35
proprioceptors
senses body position
36
cutaneous receptors
skin, touch, cold, pain, pressure and vibration
37
nociceptors
pain; responds to damage or "threat"
38
receptive field and acuity
sensory receptor in the fingertips larger areas; 2 point touch threshold the ability to distinguish the minimum distance of the 2 point touch
39
smell, taste, sight =
hearing, equilibrium
40
chemical senses
smell and taste
41
10,000 tastebuds
most are on the tongue but some are on palate, larynx, etc.
42
taste buds are found in the
papillae of the tongue
43
circumvallate
largest and most numerous
44
filiform
white fuzzy tips does not contain taste buds just for texture
45
gustatory cells
taste, chemoreceptors
46
gustatory hairs
long microvilli
47
Structural differences between tastebuds
there are none
48
5 basic taste sensations
sweet salty sour bitter umami (savory)
49
sweet
sugar alcohols, amino acids
50
salty
metal ions
51
sour
hydrogen ions
52
bitter
alkaloids
53
umami
amino acids-glutamate (meaty flavors)
54
Taste is
80% smell
55
thermo, mechano, and noci all
influence taste
56
Temperature can
enhance or distract from taste
57
Sense of smell
olfactory epithelium
58
olfactory epithelium
organ of smell covers the roof of our nasal cavity
59
Inner ear functions with
equilibrium and hearing
60
The inner ear is the
bony labyrinth and membranous labyrinth
61
The middle ear is involved with
hearing
62
the middle ear is known as the
tympanic cavity
63
the middle ear bones
ear ossicles (bones) malleus, incus and stapes (also known as the hammer, anvil and stirrup)
64
Ear Model be able to label
vestibule, cochlea, semicircular canals
65
the outer ear is involved with
hearing
66
auricle (pinna) funnels
sound
67
Ear Model be able to label
external auditory canal
68
what does the ceruminous gland produce?
wax
69
the tympanic membrane is also know as the
eardrum
70
the tympanic membrane transfers
sound energy to the middle ear
71
the tympanic membrane is the boundary between
the outer and middle ear
72
the cochlea is divided into
3 chambers scala vestibuli, scalamedia, scala tympani
73
Ear Model be able to label
scala vestibuli, scalamedia and scala tympani
74
70% of all sensory receptors are in the
eye
75
eye accessories are
eyebrows, eyelids, eyelashes and lacrimal gland
76
the eyebrows
shade sunlight, prevent sweat from going into eye
77
the eyelids
allow blinking, prevent the eye from drying out
78
the eyelashes
reflex to cause you to blink; protective to the eye
79
the lacrimal gland
secretes solution; keeps the eye moist
80
diplopia
double vision how can it be treated? exercise, wear a patch or surgery
81
sclera
protects the eye anchors extrinsic (6) muscles
82
cornea
lets light into the eye
83
choroid region
absorbs light; keeps light from reflecting and scattering
84
ciliary body
anchors the suspensory ligament that holds the lense in place
85
iris
the colored part of the eye located between the lense and cornea
86
retina
2 layered membrane that absorbs light and prevents light from scattering
87
Eye Model be able to label
optic disc (no photoreceptors; blind spot) and ganglion cells
88
optic disc
where the nerve leaves the eye
89
photoreceptors
rods and cones
90
rods respond to
dim light
91
cones respond to
bright light
92
color blindness is the
lack of one or more types of cones (blue, red or green)
93
What percentage of men are colorblind?
8%
94
What percentage of women are colorblind?
.5%
95
Most common type of color blindness is
red and green
96
Color blindness is chromosome-linked; mothers give this to their
sons
97
night blindness is caused by a prolonged
deficiency in Vitamin A
98
the lens is
biconvex transparent flexible and avascular
99
the lens allows precise
focusing of light on the retina
100
the lense is thickest in the
center
101
cataracts
the lens becomes cloudy, related to age becomes hardened and thickened
102
myopia
nearsighted
103
hyperopia
farsighted
104
presbyopia
bifocal reading glasses
105
astigmatism
unequal curvature of lens or cornea
106
Eye Model be able to label
optic disc sclera cornea iris pupil lens retina optic nerve fovea aqueous humor vitreous humor
107
Eye model be able to label
superior oblique inferior oblique superior rectus inferior rectus lateral rectus medial rectus
108
ear model be able to label
pinna (auricle) cochlea vestibule semicircular canals tympanic membrane malleus (hammer) incus (anvil) stapes (stirrup) pharyngotympanic tube (eustachian tube/auditory tube) external acoustic meatus (auditory canal)
